Well, lab leaked actually could be natural in the sense that they discovered it in the wild, brought it to the lab, then it got leaked out.
I think it would be worth knowing whether China is capable of creating a weaponized virus on their own. That would change the calculus of what kind of threat China can be.
I tend to think this wasn't a weaponized virus, but rather originated in nature, brought to the lab and leaked out. Now the question is whether the leak was intentional or inadvertent. No telling at this point.
